3 Claims.

This invention relates to a tourniquet and more particularly to a tourniquet including a device for holding an adjacent vein to facilitate travenous injections and the like.

The principal object of the invention is to provide a tourniquet which includes a readily manipulable device for pressing down upon opposite sides of a selected vein so as to hold this vein against displacement while an injection is bein-g made and also to raise the vein so a sto facilitate the insertion of a hypoderrnic needle.

Another object of the invention is to provide such a vein holding device which permits the operator to hold the vein against displacement and in a raised condition with one hand, thereby leaving the other hand free for the manipulation of the syringe.

greatly facilitate intravenous injections.

Another object of the invention is to positively prevent slipping of the vein while the injection f is being made.

In the accompanying drawing:

the vein holding device.

Figs. 2, 3 and 4 are sections taken on the correspondingly numbered lines on Fig` 1 and showing the manner in which the device is used.

Fig. 5 is a section taken on line 5--5, Fig. 2. The tourniquet is shown as comprising an elastic band ID made of rubber or the like and tached at one end to a hook II which can be of any suitable form, the hook being shown as having ears which embrace the end of the elastic band I and are pressed into iirm engagement therewith. The ends of the elastic band I0 held by a device which is shown as including a body having a curving portion I2 adapted to lie against the body of the patient and upstanding flanges I3 and I4 so that the body is U-shaped in cross section. One end of the curving portion I2 is provided with a hole I5 adapted to receive the hook II and the opposite end of the elastic band Il] is received between the two flanges I3 and I4 and held in position by a lock which comprises a latch Iii mounted on a cross pin I'I carried by the two flanges I3 and I4 and formed The (Cl. 12S- 327) latch I6 is of such length that when it is swung from the dotted to the full line position shown in Fig. 2 it engages and compresses the free end of the elastic band Ill and holds this free end against movement. The rlngerpiece I3 is of such form that when the latch I6 is moved to the full line position shown in Fig. 2 the ngerpiece I 8 engages the free end of the elastic band Iii thereby holding the latch I against movement in the direction of the pressure imposed by the elastic band I 0.

The fiange I4 of the tourniquet is formed at its outer edge to provide a laterally and outwardly extending sector or eye 2U, this sector forming a semi-circular track around which is removably hooked the hook 2I of a traveling link 22. This link or traveler 22 carries a rivet 23 at its outer end to which is pivotally secured a presser inember 2li. This presser member includes a broad part engaging the broad face of the traveler 22 anda pair of laterally projecting lingers 25 which are spaced as indicated at 26 and have their lower ends rounded or cupped as indicated' at 2l. These fingers 25 are spaced to receive between them the vein to be operated upon.

In using the tourniquet in making an intravenous injection, as illustrated in the drawing, the elastic band II) is placed around the arm of the patient about two inches above the vein to be used and the free end of the elastic band is drawn between the curving part I2 of the holder and its pin II until the required pressure is applied to the arm. The operator then presses down on the ngerpieee I8 until it engages the elastic band IU, this movement forcing the latch I6 into locking engagement with the elastic band, as illustrated by full lines in Fig. .2. The operator then takes the presser member and moves it until its ngers 25 lie on opposite sides of the vein 30 to be used. This is readily done inasmuch as the traveler 22 can move around the sector track 20 and also the presser member 24 is pivotally connected to the traveler 22. The operator then presses down upon the presser member 24, using the thumb of his left hand for this purpose, this downward pressure serving to bring the vein 30 still further into relief, as illustrated in Figs. 3 and 4. It will be seen that the use of the operators thumb in applying the pressure also serves to hold the vein against displacement. Therefore the vein is not only held against movement, but also in high relief so that the operator can readily insert the needle 3| of the syringe 32 in making an intravenous injection.

From the foregoing it will be seen that the tourniquet with the vein holding attachment forming the subject of the invention greatly facilitates intravenous injections, inasmuch as the operatori can, with one hand, hold the vein against displacement and also in high relief. It will further be seen that the device is very simple and inexpensive in construction and can easily and quickly be moved to the proper position with reference to the vein selected for use.

I claim as my invention:

1. A surgical instrument comprising a band adapted to be secured around the limb of the patient, an eye secured to said band and projecting outwardly therefrom to lie parallel with the skin of the limb, a rigid fiat metal link having a rounding hook at one end passing through said eye and formed to permit said flat linlk to be swung outwardly from the skin of the limb as well as parallel with the skin, a metal vein holding member having a flat end engaging one fiat face of said link at the free end thereof, a rivet pivotally securing said free end of said link and said flat end of said vein holding member, the free end of said Vein holding member being formed to provide a pair of spaced rounded fingers movable over a vein and into engagement with the surface of the skin on opposite sides of said vein to hold said vein against displacement and in high relief while making an intravenous injection or the like.

2. A surgical instrument comprising a band adapted to be secured around the limb of the patient, an eye secured to said band and projecting outwardly therefrom to lie parallel with the skin of the limb, a rigid flat metal linfk having a rounding hook at one end removably passing through said eye and formed to permit said at link to be swung outwardly from the skin of the limb aswell as parallel with the skin, a metal Vein holding member having a nat end engaging one flat face of said link at the free end thereof, a rivet pivotally securing said free end of said link and said flat end of said vein holding member, the free end of said vein holding member lbeing formed to provide a pair of spaced parallel iingers of substantial length projecting laterally at an acute angle relative to the plane of said flat end of said vein holding member, and a rounding end provided at the free end of each of said ngers and projecting outwardly in a direction generally parallel with said plane of said nat end of said vein holding member, said rounding ends of said fingers being engageable with the surface of the skin on opposite sides of said vein to hold said vein against displacement and in high relief while making an intravenous injection or the like.

3. A surgical instrument comprising a band having two ends, a latch secured to one end of said band and engageable with the other end to fasten said band around the limb of the patient, an eye secured to said latch and projecting outwardly therefrom to liel parallel with the skin of the limb, a rigid flat metal link having a rounding hook at one end passing through said eye and formed to permit said flat link to be swung outwardly away from the skin of the limb as well as parallel with the skin, a metal vein holding member having a flatend engaging one flat face of said link at the free end thereof, a rivet pivotally securing said free end of said link and said flat end of said vein holding member, the free end of said vein holding member being formed to provide a pair of spaced parallel fingers of substantial length projecting laterally at an acute angle relative to the plane of said flat end of said Vein holding member, and a rounding end provided at the free end of each of said ngers and projecting outwardly in a direction generally parallel with said plane of said fiat end of said vein holding member, said rounding ends of said fingers being engageable with the surface of the skin on opposite sides of said vein to hold said vein against displacement and in high relief while making an intravenous injection or the like.
